Echinacea plant named &#39;Golden243&#39;

ABSTRACT

A new and distinct cultivar of  Echinacea  plant named ‘Golden243’, characterized by its upright and relatively compact plant habit; moderately vigorous growth habit; freely branching habit; strong flowering stems; numerous large single-type inflorescences with bright golden yellow-colored ray florets and dark orange-colored receptacle spines; and good garden performance.

Botanical designation: Echinacea hybrida.

Cultivar denomination: ‘GOLDEN243’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar ofEchinacea plant, botanically known as Echinacea hybrida, and hereinafterreferred to by the name ‘Golden243’.

The new Echinacea plant is a product of a planned breeding programconducted by the Inventor in Zuidwolde, The Netherlands. The objectiveof the breeding program is to develop new freely flowering andrelatively compact Echinacea plants with unique and attractive rayfloret coloration.

The new Echinacea plant originated from a cross-pollination in July,2012 in Zuidwolde, The Netherlands of Echinacea hybrida ‘Cleopatra’,disclosed in U.S. Plant Pat. No. 24,631, as the female, or seed, parentwith Echinacea hybrida ‘Julia’, disclosed in U.S. Plant Pat. No. 24,629,as the male, or pollen, parent. The new Echinacea plant was discoveredand selected by the Inventor as a single flowering plant from within theprogeny of the stated cross-pollination grown in a controlled greenhouseenvironment in Zuidwolde, The Netherlands in July, 2013.

Asexual reproduction of the new Echinacea plant by tissue culture in acontrolled environment in Zuidwolde, The Netherlands since October, 2013has shown that the unique features of this new Echinacea plant arestable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Echinacea have been observed under all possiblecombinations of environmental conditions and cultural practices. Thephenotype may vary somewhat with variations in environmental conditionssuch as temperature and light intensity, without, however, any variancein genotype.

The following traits have been repeatedly observed and are determined tobe the unique characteristics of ‘Golden243’. These characteristics incombination distinguish ‘Golden243’ as a new and distinct Echinaceaplant:

-   -   1. Upright and relatively compact plant habit.    -   2. Moderately vigorous growth habit.    -   3. Freely branching habit.    -   4. Strong flowering stems.    -   5. Numerous large single-type inflorescences with bright golden        yellow-colored ray florets and dark orange-colored receptacle        spines.    -   6. Good garden performance.

Plants of the new Echinacea can be compared to plants of the femaleparent, ‘Cleopatra’. Plants of the new Echinacea differ from plants of‘Cleopatra’ primarily in ray floret color as ray florets of plants of‘Cleopatra’ are soft yellow in color. In addition, plants of ‘Cleopatra’are more freely branching than plants of the new Echinacea.

Plants of the new Echinacea can be compared to plants of the maleparent, ‘Julia’. Plants of the new Echinacea differ from plants of‘Julia’ primarily in ray floret color as ray florets of plants of‘Julia’ are orange in color. In addition, plants of ‘Julia’ are morefreely branching than plants of the new Echinacea.

Plants of the new Echinacea can be compared to plants of Echinaceapurpurea ‘Avalanche’, disclosed in U.S. Plant Pat. No. 18,597. Inside-by-side comparisons conducted in Zuidwolde, The Netherlands, plantsof the new Echinacea differed primarily from plants of ‘Avalanche’ inthe following characteristics:

-   -   1. Plants of the new Echinacea were shorter than plants of        ‘Avalanche’.    -   2. Plants of the new Echinacea were not as freely branching as        plants of ‘Avalanche’.    -   3. Plants of the new Echinacea and ‘Avalanche’ differed in ray        floret color as ray florets of plants of ‘Avalanche’ were white        in color.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs illustrate the overall appearance of thenew Echinacea plant showing the colors as true as it is reasonablypossible to obtain in colored reproductions of this type. Colors in thephotographs may differ slightly from the color values cited in thedetailed botanical description which accurately describe the colors ofthe new Echinacea plant.

The photograph on the first sheet is a side perspective view of atypical flowering plant of ‘Golden243’ grown in ground beds in anoutdoor nursery and placed in a 17.5 cm by 22 cm container for thephotograph.

The photographs on the second sheet are close-up views of a typicalinflorescence (upper photograph) and the upper surface of a typical leaf(lower photograph) of ‘Golden243’.

DETAILED BOTANICAL DESCRIPTION
